Backuppc Hostcheck für Ubuntu und Gentoo

Das offizielle Checkscript von Backuppc das überprüft ob alle Rechner gebackuped sind ist veraltet und nicht brauchbar. Das Script wurde für Gentoo und Ubuntu umgeschrieben. Folgender Eintrag muss jeweils in die /etc/suduers:

nagios    ALL=(backuppc) NOPASSWD: ALL

Die Scripte werden jeweils in das Nagios Pluginverzeichnis kopiert.

  #
  ########################################################################
  #
  # Installation (nagios client side) :
  # - Copy the script in your nagios plugins directory (usualy /usr/lib/nagios/plugins)
  # - Set good rights (700 for nagios user)
  # - Add those two lines in your suoders file :
  #   - "Cmnd_Alias  GETSTATUS = /bin/su - backuppc -c /usr/share/backuppc/bin/BackupPC_serverMesg (or replace by your $bppccmd value bellow) 'status hosts'"
  #   - "nagios  ALL=NOPASSWD:GETSTATUS"
  #
  # Usage : check_backuppc_hosts [path_to_BackupPC_serverMesg]
  #         - path_to_BackupPC_serverMesg : if unset, default is /usr/share/backuppc/bin/BackupPC_serverMesg
  #
  ########################################################################
  #
  # History :
  #
  # v0.2 :
  # + Added number of backuped hosts in status information column
  # + Added number of hosts errors in status information column
  # + Added an unknow host detection (from host backuppc file)
  # = Check hosts method optimized ((x hosts) * (time to check) faster)
  # = Improved security on sudoers command
  #
  # v0.1 :
  # + First version
